Description

[0002] Grasslands, as an important ecological barrier and natural resource treasure trove in my country, not only play a key role in maintaining regional ecological balance, but also serve as the foundation for the livelihoods of the vast number of herders.

[0003] Currently, domestic research on root cutting and soil loosening techniques for degraded grassland improvement is relatively limited, with most studies referencing traditional farmland loosening machinery. However, the unique root-soil complex structure of degraded grassland significantly enhances soil shear strength and strengthens its resistance to external forces. This results in technical bottlenecks for traditional grassland loosening machines, such as high root cutting resistance and difficulty in soil breaking, leading to poor effectiveness in breaking up dense root tangles and improving soil permeability, thus failing to meet the actual needs of degraded grassland ecological restoration. Therefore, there is an urgent need to develop a combined machine that actively breaks up root tangles and improves soil permeability to solve the challenges of degraded grassland ecological restoration. Summary of the Invention

[0053] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0054] (1) An innovative linkage operation mode of soil permeability device and grass root breaking device is adopted. During the movement of the machine, the grass root breaking device works in coordination with the grass root breaking vibration device of the soil permeability device to achieve an organic combination of horizontal displacement and high-frequency reciprocating motion in the vertical direction. This design not only significantly increases the working coverage area of ​​the grass root breaking device and effectively improves the soil permeability of saline-alkali grassland, but also greatly reduces the tillage resistance through dynamic operation mode, significantly improving the operating efficiency and energy utilization efficiency of the equipment.

[0055] (2) Using the hinge point between the loosening blade and the loosening blade holder as a support point, the loosening unit and the loosening vibration device of the soil permeability device form a cam crank mechanism. As the eccentric wheel continues to rotate, the loosening blade, relying on this hinge point, achieves rhythmic reciprocating motion in the front-back direction during the machine's forward operation. This unique motion mode significantly reduces the resistance encountered during the loosening process, effectively reducing equipment energy consumption; on the other hand, it greatly enhances the loosening effect, more fully breaking up soil clumps, improving soil structure, and laying a good foundation for subsequent planting or improvement work.

[0056] (3) Both the grass root breaking vibration device and the soil loosening vibration device of the present invention adopt an adjustable eccentric structure design. By precisely controlling the relative position of the two sets of eccentric wheels, the cooperative operation mode of the grass root breaking unit and the soil loosening unit can be changed. When synchronous operation is required, the eccentric position can be adjusted to start both at the same time. If intermittent operation is required, alternating operation can also be achieved by adjusting the parameters.

[0057] (4) By independently adjusting the grass root tangling vibration device or the soil loosening vibration device, the corresponding individual units can present a variety of movement patterns, including synchronous movement, spiral intermittent movement and group intermittent movement. This highly flexible adjustment mechanism can accurately adjust the eccentric axis position parameters according to the soil characteristics and improvement needs of different degraded grasslands, optimize the movement combination of grass root tangling and soil loosening units, and thus achieve the best grassland improvement operation effect.

[0122] Working principle of the invention:

[0123] Please see Figures 1-8 The working principle of a combined active-powered weed root breaking and soil permeation machine is as follows: The entire machine is attached to the rear of a tractor via a gantry frame 2, and the depth of the machine entering the soil is adjusted using depth-limiting wheels 3. The front gearbox 4 is fixedly connected to the frame A, and the tractor's rear output shaft is connected to the front gearbox 4 via a coupling. One end of the front drive shaft 6 is connected to the front gearbox 4 via a universal joint coupling, and the other end is connected to the side transmission mechanism 5 via a universal joint coupling. Simultaneously, the front gearbox 4 is connected to the intermediate gearbox 7 via a sprocket coupling. During machine operation, the front gearbox 4 drives the side transmission mechanism 5 and the intermediate gearbox 7 to rotate.

The left front gearbox 13 transmits power to the left rear gearbox 14 via a sprocket coupling. The left rear gearbox 14 drives the soil loosening vibration device 15 to rotate. The adjacent soil loosening vibration device 15 rotates together with its left side soil loosening vibration device 15 via a sprocket coupling.

[0124] Please see Figures 9-11The connecting flange 18 is fixedly connected to the side transmission mechanism 5. The side transmission mechanism 5 drives the hexagonal transmission cutter shaft 19 through the connecting flange 18. The cutter shaft connecting transmission shaft 22 is sleeved on the hexagonal transmission cutter shaft 19, driving the bevel gear transmission shaft 23. The bevel gear transmission shaft 23 transmits power to the grass root breaking and coiling cutter shaft 24, which in turn drives the grass root breaking and coiling flange 29 and the grass root breaking and coiling cutter disc 30 to rotate together, realizing the grass root breaking and coiling operation. The grass root breaking and coiling sleeve 25 is sleeved on the cutter shaft connecting transmission shaft 22, bevel gear transmission shaft 23 and grass root breaking and coiling cutter shaft 24, and plays a protective role. At the same time, the grass root breaking and coiling sleeve 25 is connected to the hexagonal transmission cutter shaft 19 through bearings, so that the grass root breaking and coiling unit 21 can rotate around the hexagonal transmission cutter shaft 19. A connecting base 31 is fixed on the grass root breaking sleeve 25. The connecting base 31 is hinged to the guide rod 33, and the guide rod seat 32 is connected to the frame A. The clamping force applied by the spring between the connecting base 31 and the guide rod seat 32 provides an adaptive adjustment function for the grass root breaking unit 21. During machine operation, this adjustment mechanism allows the grass root breaking unit 21 to automatically adjust the soil penetration depth of the grass root breaking cutter disc 30 by a small range according to the real-time changes in soil resistance.

[0125] Please see Figure 12 and Figure 13 The vibrating device 8 for breaking up grass roots and knots contacts the guide rod 33 of the grass-breaking unit 21. As the eccentric shaft 10 rotates, the grass-breaking unit 21 reciprocates in the up-down direction. During the mechanical movement, the grass-breaking device 8 and the vibrating device 8 work together to achieve an organic combination of horizontal displacement and high-frequency reciprocating motion in the vertical direction of the grass-breaking unit 21, which greatly reduces tillage resistance and significantly improves the equipment's operating efficiency and energy utilization efficiency.

[0126] Please see Figure 14 and Figure 16 The soil loosening device D uses the hinge point between the loosening blade 37 and the loosening blade holder 36 as a support point, forming a cam-crank mechanism with the loosening unit 35 and the loosening vibration device 15. As the eccentric shaft 10 rotates continuously, the loosening blade 37, relying on this hinge point, performs rhythmic reciprocating motion in the forward and backward directions during the machine's forward operation. This unique motion significantly reduces the resistance encountered during soil loosening and greatly enhances the loosening effect, more thoroughly breaking up soil clumps and improving soil permeability, laying a good foundation for subsequent planting or improvement work.

[0127] Both the root-breaking vibration device 8 and the soil-loosening vibration device 15 adopt an adjustable eccentric structure design. By adjusting the relative position of the two sets of eccentric shafts 10, the collaborative operation mode of the root-breaking vibrator 21 and the soil-loosening vibrator 35 can be changed. When synchronous operation is required, the eccentric position can be adjusted to start both at the same time; if intermittent operation is required, alternating operation can also be achieved through parameter adjustment. Moreover, independently adjusting the root-breaking vibration device 8 or the soil-loosening vibration device 15 can make the corresponding units present diverse movement patterns, covering multiple modes such as synchronous movement, spiral intermittent movement, and group intermittent movement. The movement combination of the root-breaking vibrator 21 and the soil-loosening vibrator 35 can be optimized according to the soil characteristics and improvement needs of different degraded grasslands, thereby achieving the best grassland improvement operation effect.
